Specification of Letters Patent.

Patented-Mar. 4, 1913.

Application filed July 29, 1909. Serial No. 516,252.

To all uito/nit may] concern:

Be it known that I, HUBBARD N. JosLnYn, a citizen of the United States, and residentof Syracuse. in the county of Onondaga and State of New ,York, have invented certam new and useful Improvements in Type- :Writing Machines, of which the following 153 a specification.

My invention relates more particularly to the bearings for the type bars of typewriting machines, and has for itsmam ob ject to provide an improved construction of type barhanger and one which while occupying a small space laterally considered,

yet, at the same time, furnishes a broad and stable bearing forthe type bar. A

To these ends the invention consists in the features of construction, combinations cent-rally, of a typewriting machine embodys ing my invention, parts of the machine being omitted. Fig. 2 is a fragmentary front elevation taken on a plane represented by the line a; min Fig. 1, some parts not shown in said Fig. 1 being added and other parts shown in said Fig. 1. being omitted. Fig.

3 is an enlnr ed sectional View, taken on a horizontal p ane passing through the cen ter of rotation of the type bar shown in Fig. 1. Fig. 4 is a fragmentary view of the type bar and hanger'talren on a plane represented by the line f y in Fig. 3 Fig. is a detail view of the type bar bearing plates.

In the drawings the main frame of the machine is SllOWl'i as comprising a base 1, corner posts 2 and a top plate 3. Key levers l are fulcrumed 5 in t. 6 rear of the base, each of said hey levers being provided with a restoring spring 6.

7 with each key lever is a sub-lever 8, the

end whereof is slotted to co-act with a lined abutment 9 and the upper end whereof is connected by a link 10 with a type bar 11 which is mounted in a manner presently to be described in a type bar hanger 12. Th han r 3.2 is oi series or": hangers seghan ally a in radial sl or 'lgerfis l3. ii t*l'll8 front giace of: ginental Pivot-ally connected type bar support 14. The segmental support 14 is connected with a known form of shifting mechanism, but for the purposes of this invention it is immaterial whether the segment 14. be shiftable or nonshiftable; and the type bars are designed to move upwardly andrearwardly to co-act with the front face of a platen 15, but, considered in its broader aspects it is immaterial for my purposes whether the invention is embodied in a front strike typewriting machine, as shown, or in some otherkind or style of writing machine.

Each hanger 12 is bifurcated, the bifurcations or side walls 16 and 17 being joined at the bottom by'a web or base portion 18 from which depends a shank or stem 19 provided with a cam slot 20. The shank or stem 19 of each hanger fits into one of the radial slots 13 in the segmental support 14, and thecam slot 20 receives a set screw 21 by hich the hunger is. secured in place, the end of said set screw abuttin portionof the slot 20 so that as said set screw is screwed in tight it serves to firmly seat the hanger with theweb 18 in contact with the top of the segment 14. 4 g I The side walls 16 and 17 of thehanger are perforated to receive a plurality of rivets 22, which are preferably four in number. Two bearing plates 23 substantially sectoral in shape, have their outer circularly curved edges formed with a double beveled portion 24 and their inner circularly curved edges formed centrally with a single beveled portion 25 having a greater inclination than the bevels 24.. Each bearing plate formed with perforations 26 somewhatlarger in diameter than the rivets 22, said rivet-s passing through the perforations26 and serving to connect the bearing plates loosely with the side walls of the hanger. An adjusting screw 27 having a head coned on the under side passes from the wall 16 to the wall 17 of the hanger, being received in perforations in said walls andbein arranged so that the coned portiono the head contacts with the beveled portions 25 ice of the bearing plates 23 It will be-noted that the erforation the screw 2? in the plate [17 is threaded to receive the threaded shank of saidscrevn while the head fiftli'e saidlscrcw acting on the beveled edges-25 to l liar may turn freely on the bearing plates larger than the rirets 227 'plane is themeclian plane of the type nor; Jihainthe bearing plates are ad ustable in ing a bearing part. or parts attached to it ower? screw passes through a lar er plain perforation in the Well 16. The pivotal end ofthe type bar 11 is provided with an eye 28, the edge of which is formed with a V-shaped groove 29 which receives the outer beveled edges :24: of the bearing plates 23.

In assembling the parts the bearing plates :13 are preferably inserted in the eye 28 in the type bar 11 which-is then positioned between t-lie bearing walls 16 and 17 of theeyeless member or hanger. It will he noted from an inspection of Fig. 3 that the bearing plates :23 are of such width that they fit snugly between the hanger walls L6 and 17, While the type bar is somewhat narrower and does not Contact with the inner faces of paid hanger walls. The rivets 22 are next passed from one bearing Wall to the other and through the perforations 26 in the bearing plates, after which said rivets are headed so that the bearing plates are loosely but permanently mounted in the hanger. The adjusting screw-27 is then screwed into place, the coned portion of cam the bearing plates 23 ontwarllfvor away from the axis of rotation-so that the beveled edges 2% of thebearingplates engage (no Vslxaped grome int-he eye 28 of the type bar in such wise that. said type although the fit is; ani'iicirnt-ly.snng to take up all unnecessary looseness and to maintain tlicflype bar properl) alined.

In order to take up wear between the hearing plates aml the type bar it is onlv necessary lo ti ll'ill the adjusting; arrow 27, thereby causing: ilio hearing plates to move outwardly inlho eye of. the type liar, such movement being possible because of the fact that the peri'm'atmxns 26 are somewhat It will be observed that the beari= plates are at diametrically opposite Sllltl of the axis of rotation of the type liar; that said bearing plates are in the same plane transverse of said axis of rotzxtiorr; ll1at eaitl said plane and transversely of the axis of said type bar; that the type bar hangers as I construct them are compa 'ativcly narrow so that they may be assembled close together on the segment, as best seen in 2 Whllt at. the some time they provide a Wide bearing for the type bars tlnis conclucing ":0 the stability of the latter; that by my in-' vention a typebar hanger is pro'videcl havand cooperating with the eye in the type bar and movable away from the axisof motion by means separate from the means which snnport the part or parts \Vhlfjli:
